ITEM_BLOCKED_BY_GATING

Solution:

It is classified as a restricted category for your seller account and therefore the ASIN cannot be sold. To request approval for selling this item, please add it manually by clicking here (The link will redirect you to Seller Central). Once approved, you will be able to add it again. If you encounter the same error even after manually adding it on Amazon Seller Central, it may indicate an Amazon API issue. We recommend trying to add this item again the next day.

**Please note that creating a new SKU for the ASIN is unnecessary. Amazon granting approval to sell the category, brand, or item should be sufficient to resolve the error.
